hello
i can't activate left column in my prestashop 1.6
it's a updated version (from 1.5.6.2)
i go to preferences > themes then i click on "default bootstrap" theme, and i see page to configure the columns visibility, when i want to enable or disable column i see:
[color=rgb(104,115,127);font-family:Arial, Helvetica, sans-serif;font-size:13px;]"An error occurred while updating this meta"[/color]
no matter what and where i click.
